The westbound lanes of I-64 from Waddy to Shelbyville were shut down from dawn to early afternoon Thursday when a tractor-trailer caught fire after striking a vehicle parked on the shoulder of the road.

Shelby County Assistant Fire Chief Jeff Ivers said that he was not at the scene, but he said he understood that no one was injured in the incident, which happened when a tractor-trailer clipped a car that had been abandoned on the side of the road near Mile Marker 36.

The driver of the truck, whose identity has not been released, was able to escape before flames fully destroyed the cab and most of the cargo area of the truck. Shelby County Emergency Management Director Paul Whitman, who was at the scene, said the truck had clipped a sports-utility vehicle that had been abandoned about a half-mile east of Mount Eden Road.

Officials from Department of Vehicle Enforcement have not returned phone calls.

The crash, reported at 7:06 a.m., caused a rush-hour backup of about 5 miles, almost to the Waddy/Peytona exit. Both westbound lanes remained closed until after 1 p.m.

Motorists began detouring down U.S. 60 to get into Shelbyville, but traffic along KY 395 between Waddy and Peytona was bumper-to-bumper, and traffic on U.S. 60 was backed up almost to Clay Village.

That problem was exacerbated by an accident at Boone Station an U.S. 60 that required Shelby County Sheriff’s deputies to direct traffic.
